An amusing video has emerged of a woman playing a revenge prank on her boyfriend by putting wasabi sauce into his toothpaste. <br /><br />The footage was captured by Rebekah in a house in Milton Keynes, UK in May. She'd previously fallen victim to a 'ketchup bomb' and other pranks from him so decided to get her own back. <br /><br />Se can be seen hiding outside their bathroom as Reuben goes to brush his teeth, filming his reaction as he swears and spits.<br /><br />The pair's "prank" war has been going on for several months.<br /><br />+++CLIENTS PLEASE NOTE: Edited for swearing+++
